I've occasionally stopped by to see the remains of the Teignmouth Electron.  This was a trimaran sailboat owned by Donald Crowhurst and employed in his 1969 attempt to sail around the world, solo and nonstop as part of the Sunday Times Gold Globe Race.  I'm not really sure how long it has been lying on the beach near the Kidco Dock, but since at least 1988, when Hurricane Gilbert hit Cayman Brac, as this was the storm that beached the 'Barbara Ann'. 

If you wish to find it on Google Earth, its Longitude & Latitude Coordinates are:   19°41'10.40"N by  79°52'37.83"W
